‘Lip Sync Battle’ Sneak Peek: All Four Fifth Harmony Members Fight for the Championship Belt (VIDEO)

Fifth Harmony is hilarious (and totally on fire) in previews for a special four-way edition of Lip Sync Battle set to air February 1.

The girl group's four members—Normani Kordei, Lauren Jauregui, Ally Brooke and Dinah Jane—will go head-to-head on Thursday, with Brooke performing a medley of Selena and Jennifer Lopez songs, and Jane singing "You're Welcome" from Disney's Moana, complete with Maui drag. (Fun fact: Back in 2015, it was rumored that Jane, who is of Polynesian descent, might be cast as the titular princess in the animated film.)

In the wise words of Kordei: "I was not expecting any of it!"

Meanwhile, it looks like Jauregui will pay tribute to the late Amy Winehouse, while Kordei plans to get bootylicious. (Peep that big "House of Booty" sign!)

See clips from two of the performances, below, and catch Lip Sync Battle on Spike this Thursday at 10 p.m. ET.
